Our Uniqueness
We have a long history of close collaboration with the MAA‘s American Mathematics Competitions (AMC), which are dedicated to strengthening the mathematical capabilities of our nation’s youth, and are the first of a series of competitions in high school mathematics that determine the United States team for the International Mathematical Olympiad (IMO).
We are only one in the Washington DC metropolitan area to offer elementary, middle, and high-school level competition math courses. Our students have received top scores and awards at prestigious national math competitions.
Great Benefits of Math Competitions
In an increasingly competitive college application pool, the process of mastering math skills through our courses and participating in the American Math Competitions will help students strengthen and diversify their extracurricular activities. These contests can motivate students’ interest and passion in math, and they can discover their talent through solving challenging problems different from those in the school classes. Many top colleges also request AMC scores as part of the college application process. Both MIT and Caltech have entry blanks on their official admission application forms for the applicant to enter their best AMC and AIME scores. Ivy League Colleges, Caltech, and Stanford ask for to the AMC and AIME scores in their Supplement to the Common Application Forms. Your children deserve the chance to list these scores on their applications! Good AMC scores will greatly enhance admission opportunities for students to elite colleges.

This year’s AMC 8 contest contains 5 number theory problems and 6 counting & probability problems. In last year’s AMC 8/MathCounts Prep Summer Weekend Course about Discrete Math (Number Theory, Counting, and Probability), what we comprehensively presented fully covered all the geometry topics that appeared in the 2024 AMC 8 test. All Discrete Math problems on the 2024 AMC 8 are the same as or very similar to the typical examples demonstrated in our Summer Course so that our students can become very familiar with them and fully master those powerful methods to solve them. This is how our course can greatly help our students to get a high score on the AMC 8 contest!
You are very welcome to sign up for our online course which offers a quick, efficient way for students to interact with teachers over long distance. We use the Google Meet to video chat and easily connect with students to teach them our tricks and shortcuts to getting an amazing score on their contests, as well as offer them our guidance and support. Students can ask questions face-to-face via Google meet, and can complete problems with the supervision of our teachers/coaches. Click HERE to see detailed instruction.
A commitment to the whole course can maximize the benefit of learning all the math ideas, methods, strategies, tactics, skills, and techniques. Click HERE to see attendance/absence/aancellation/makeup lesson policy

To become one of the top winners in the individual competition at the chapter level and then advance to the state competition.

There are many math competitions in the United States. Of those, only
AMC → AIME → USAMO sequence
would take you to the IMO (International Math Olympiad), the highest level math competition for high school students in the world!

Description:
Our curriculum focuses on advancing the mathematical skills of 5th-8th graders to prepare them for math competitions, such as AMC 8, AMC 10, Mathcounts, Math Olympiads for Elementary and Middle Schools (MOEMS), Math Kangaroo, and Math League. A variety of contest questions, including all past official AMC 8 problems, the first 15 problems on each old AMC 10 tests, and MathCounts Competition problems at the school, chapter, state, and national level, are used to teach students strategies to solve problems and help students prepare for the competitions. These problems stimulate their interest and enthusiasm for critical thinking and problem solving, broaden their mathematical intuition, and develop their brainpower. The topics taught in this class are not covered in regular school math classes, allowing our students to stay one step ahead.

Benefits:
Grade Levels: Rising Grades 4-8

This class focuses on efficient tricks, shortcuts, and strategies to solve competitive math problems as well as test-taking tactics. The emphasis of this class will be on comprehensively problem-solving in discrete math (number theory, counting, and probability), which is the most important to competitive math. We reserve the right to adjust the teaching content and pace according to the actual performance of students .

On average, at least 6 hours per week, as described in the article: Homework assignments are a fundamental part of our courses. Click HERE to see a typical homework sample we developed. Each week, we will carefully review and check 3 students’ homework, and correct any mistakes. The next week, we will check another 3 students’ homework, and this will continue on a rotational basis until all students have had their homework checked at least once and the cycle will start again. Based on the work of the 3 students that week, we will provide the those 3 students with individualized proposal and support. More details can be found in the article: Homework Correction is very Important — We Give an Extensive Correction of the Incorrect Answers of All Homework.

We have to face the simple truth that to do well on these grueling contests, we will need to practice. Just like it is for sports and music, the key to success is repetition and practice. We strongly believe in effort and the malleability of intelligence. Intelligence can be enhanced through effort. People can develop impressive levels of expertise through hard work and practice. Effort and persistence are the keys to success. Hard work always pays off: practice makes perfect!
All problems from past AMC 8 exams (1985-2024), AMC 10 exams (2000-2023), and MathCounts (1990–2024) form our “big data” system. Based on artificial intelligence (AI), machine learning, and deep learning, we devised a data mining and predictive analytics tool for math problem similarity searching. Using this powerful tool, we examined the types, styles, frequencies, characteristics, and traits of questions in all these materials, and then completely “decoded” the AMC, and MathCounts. We always completely show all the “secret code” cracked from the above big data to our students, and teach them to totally grasp and “control” the AMC and MathCounts. For all questions on the recent AMC/MathCounts contests, we can find their “ancestors” and “roots” from the old AMC/MathCounts problems. Therefore, the best way to prepare for the contest is to practice by solving old AMC/MathCounts problems.

Main Purpose:
Our main purpose is to help our students gain deeper understanding of the fundamental math concepts, build a solid foundation in math, and develop the critical thinking and problem-solving skills that are so valuable to success in any career. We are big believers in the FUNDAMENTALS! Our students will receive the LIFELONG BENEFITS from learning math.
Regardless of his/her math level, each student will have the opportunity to learn math in a fun, friendly, cooperative, supportive learning environment. The most important thing is to have fun, playful, and enjoyable!

We have a long history of close collaboration with the MAA’s American Mathematics Competitions (AMC), which are dedicated to strengthening the mathematical capabilities of our nation’s youth, and are the first of a series of competitions in high school mathematics that determine the United States team for the International Mathematical Olympiad (IMO).
We are only one in the Washington DC metropolitan area to offer elementary, middle, and high-school level competition math courses. Our students have received top scores and awards at prestigious national and math competitions.
Great Benefits of Math Competitions
In an increasingly competitive college application pool, the process of mastering math skills through our courses and participating in the American Math Competitions will help students strengthen and diversify their extracurricular activities. These contests can motivate students’ interest and passion in math, and they can discover their talent through solving challenging problems different from those in the school classes. Many top colleges also request AMC scores as part of the college application process. Both MIT and Caltech have entry blanks on their official admission application forms for the applicant to enter their best AMC and AIME scores. Ivy League Colleges and Stanford ask for to the AMC and AIME scores in their Supplement to the Common Application Forms. Your children deserve the chance to list these scores on their applications! Good AMC scores will greatly enhance admission opportunities for students to elite colleges.

Small-sized Class Teaching Model:
We utilize the highly effective small-sized class teaching model. Smaller classes lead to pupils receiving more individual attention from teachers, and having more active interactions with them. We focus on every individual, not the whole class. Students will thrive from the smaller class sizes that allow them to reach their full potential. Particularly, students can benefit tremendously from high-frequent individualized student-teacher interactions leading to establishment of a stronger foundation for lifelong learning.
Our main purpose is to help our students gain deeper understanding of the fundamental math concepts, build a solid foundation in math, and develop the critical thinking and problem-solving skills that are so valuable to success in any career. We are big believers in the FUNDAMENTALS! Our students will receive the LIFELONG BENEFITS from learning math.

Regardless of his/her math level, each student will have the opportunity to learn math in a fun, friendly, cooperative, supportive learning environment. The most important thing is to have fun, playful, and enjoyable.

We have a long history of close collaboration with the MAA’s American Mathematics Competitions (AMC), which are dedicated to strengthening the mathematical capabilities of our nation’s youth, and are the first of a series of competitions in high school mathematics that determine the United States team for the International Mathematical Olympiad (IMO).
We are only one in the Washington DC metropolitan area to offer elementary, middle, and high-school level competition math courses. Our students have received top scores and awards at prestigious national and math competitions.
Great Benefits of Math Competitions
In an increasingly competitive college application pool, the process of mastering math skills through our courses and participating in the American Math Competitions will help students strengthen and diversify their extracurricular activities. These contests can motivate students’ interest and passion in math, and they can discover their talent through solving challenging problems different from those in the school classes. Many top colleges also request AMC scores as part of the college application process. Both MIT and Caltech have entry blanks on their official admission application forms for the applicant to enter their best AMC and AIME scores. Ivy League Colleges and Stanford ask for to the AMC and AIME scores in their Supplement to the Common Application Forms. Your children deserve the chance to list these scores on their applications! Good AMC scores will greatly enhance admission opportunities for students to elite colleges.

Specific Goal:
To earn a score of 100 or more out of 150 on the American Mathematics Contest 12 (AMC 12), and then qualify for the American Invitational Mathematics Examination (AIME), which is used to determine qualification for the United States of America Mathematical Olympiad (USAMO).

There are many math competitions in the United States. Of those, only
AMC → AIME → USAMO sequence
would take you to the IMO (International Math Olympiad), the highest level math competition for high school students in the world!
Who should take this class: This class is very appropriate for raising 6th-12th grade students who are hoping to qualify for the AIME.
Benefits:
Weekly Homework:
At least 6 hours per week. Problem sets include all problems on the past AMC 10/12 and ARML, and 500 brand new problems having similar difficulty and style as the real AMC 10/12 problems, extracted from the licensed AMC Database.
The focus will on the final 15 problems on the AMC 12, and the first 5 problems on the AIME, as well as those hard problems on the ARML. Note that some hard problems on the recent AMC 10 and 12 are exactly the same as previous ARML Problems.

| We reserve the right to adjust the teaching content and method according to students’ understanding and comprehension of new knowledge. | ||

Small-sized Class Teaching Model:
We utilize the highly effective small-sized class teaching model. Smaller classes lead to pupils receiving more individual attention from teachers, and having more active interactions with them. We focus on every individual, not the whole class. Students will thrive from the smaller class sizes that allow them to reach their full potential. Particularly, students can benefit tremendously from high-frequent individualized student-teacher interactions leading to establishment of a stronger foundation for lifelong learning.
Our main purpose is to help our students gain deeper understanding of the fundamental math concepts, build a solid foundation in math, and develop the critical thinking and problem-solving skills that are so valuable to success in any career. We are big believers in the FUNDAMENTALS! Our students will receive the LIFELONG BENEFITS from learning math.

Regardless of his/her math level, each student will have the opportunity to learn math in a fun, friendly, cooperative, supportive learning environment. The most important thing is to have fun.

Description:
We will reveal powerful mental math techniques that allow you to perform calculations in your head quickly and effortlessly. You will learn to compute faster than you ever imagined, and with practice, your ability to retain and manipulate numbers will improve significantly. These techniques will not only enhance your mathematical skills but also enable you to perform impressive mental feats that will amaze your friends, colleagues, and teachers. Most importantly, you will discover that math can be fun, engaging, and deeply rewarding.
Too often, math is taught as a set of rigid rules, leaving little room for creativity and exploration. However, as you will see in this course, many problems can be solved in multiple ways. By breaking down complex problems into smaller, more manageable parts, we can simplify calculations and uncover clever shortcuts. We also learn to spot patterns and special features that make problem-solving more efficient. These strategies are not just valuable for mathematics — they serve as critical thinking skills that can be applied to problem-solving in everyday life.
One often-overlooked benefit of mental math is that it sharpens your ability to think quickly and make rapid decisions. Based on our years of teaching experience, we have found that speed and accuracy in mental calculations are essential skills that anyone can develop with proper practice. Like any worthwhile ability, mastering mental math requires dedication and strategic practice — but with the right approach, you can achieve remarkable results.
For students competing in mathematics competitions, slow calculation speed and low accuracy are among the biggest obstacles to success. Our program is designed to equip students with effective problem-solving strategies, boost computational speed, and enhance accuracy, ensuring they are well-prepared to excel in competitive mathematics.

The widespread use of calculators has introduced significant challenges to mathematics education. In primary and middle schools, excessive dependence on these devices is eroding students’ foundational mathematical abilities.
Mathematics education is not merely about performing calculations — it is about cultivating logical thinking and problem-solving skills. When students become accustomed to obtaining answers by simply pressing buttons, they lose the valuable process of reasoning through problems. A simple arithmetic operation, when solved mentally, requires an understanding of the order of operations, carrying and borrowing rules, and number relationships. These seemingly basic processes are, in fact, the cornerstone of mathematical thinking and cognitive development.
The Consequences of Over-Reliance on Calculators
Excessive use of calculators leads to a decline in students’ mathematical abilities. Research shows that students who rely heavily on calculators tend to have significantly weaker mental calculation skills than their peers who use them sparingly. This weakness is not just in calculation speed but also in number sense and conceptual understanding. When students lose their intuition for numbers, they struggle to solve complex mathematical problems that require deeper reasoning.
The premature introduction of calculators in primary and middle school creates a dependency that can be difficult to break. What begins as a reliance on calculators for basic arithmetic gradually turns into an inability to perform even the simplest calculations without them. Many students lose confidence in their ability to compute manually, feeling the need to verify even basic sums with a calculator. In extreme cases, this over-reliance cripples their fundamental calculation skills, leaving them unable to perform mental or written arithmetic efficiently.
A Phased Approach to Calculator Use
To address this issue, we advocate for a phased approach to calculator use in education:
During the critical years of mathematical development, students should be guided to establish a strong foundation through mental and written calculations. Developing mental arithmetic skills is not just about improving speed; it is about enhancing logical thinking and problem-solving ability. Primary school should be the stage where students solidify their number sense, while middle school should focus on further strengthening these skills before gradually introducing calculators in a controlled manner.
The Impact of Banning Calculators in Math Competitions
As is well known, prior to 2008, the American Mathematics Competitions (AMC) allowed students to use calculators. However, after our persistent appeals and protests, the Mathematical Association of America (MAA) implemented a landmark policy change prohibiting calculator use in AMC starting in 2008. This decision forced students to develop stronger mental and rapid calculation skills, significantly improving their overall mathematical abilities.
The ban was based on the realization that calculators were hindering the development of fundamental arithmetic skills. By removing this crutch, students were compelled to engage more deeply with numerical concepts, developing stronger intuition for numbers and a deeper understanding of mathematical principles. As a result, students not only became more proficient in calculations but also sharpened their problem-solving and logical reasoning skills — essential abilities for success in mathematics and beyond.
Training Students for Mental and Quick Calculation
To support this transition and further enhance students’ mathematical skills, we have introduced specialized training programs. Every summer, we offer intensive courses designed to help students improve their mental and rapid calculation abilities. More details can be found at Online Intensive Mental Math Course (Summer Session). These programs provide a structured environment where students refine their skills through a series of progressive exercises and challenges.
The impact of these initiatives has been profound. Students who participate in our summer programs consistently demonstrate remarkable improvements in their mathematical performance. They develop a greater appreciation for the beauty and logic of mathematics and gain the confidence to tackle complex problems without relying on calculators. By fostering a generation of students proficient in mental calculations, we are not only boosting their academic achievements but also preparing them for future success in fields that demand strong analytical and quantitative skills.
Conclusion
Mathematics education is fundamentally about nurturing thinking skills, and over-reliance on calculators is a major obstacle to achieving this goal. The prohibition of calculators in math competitions, along with structured training programs, has played a pivotal role in enhancing students’ mathematical abilities. These efforts reaffirm our commitment to building a generation of mathematically proficient individuals, equipped to excel in an increasingly competitive and data-driven world.
By reducing dependence on calculators and reinforcing mental arithmetic, we can ensure that students develop deep mathematical intuition, problem-solving abilities, and logical reasoning skills — qualities that will benefit them not only in academics but throughout their lives. Let us safeguard the integrity of basic education and lay a strong mathematical foundation for future generations.

The true key to mastering mathematics lies in transforming knowledge from something external — merely memorized — into an internalized skillset that becomes second nature. To achieve this, students must go beyond rote learning and actively engage in a process of deep comprehension and creative exploration.
Step 1: Recall — Testing Your Understanding
After attending a math class, immediately review the concepts covered without referring to any materials. Try to recall the key points discussed by the teacher, including formulas, theorems, and their derivations. The ability to reconstruct this information from memory is the best test of how effectively you absorbed the material during class. If you struggle to recall certain details, it signals areas that require further review.
Step 2: Derivation — Reinforcing Knowledge Through Independent Thought
Take out a notebook and write down the important formulas and theorems from memory. However, do not stop at simply writing them down — challenge yourself to re-derive the formulas and prove the theorems using your own thought process. This independent thinking exercise helps pinpoint gaps in your understanding and solidifies your grasp of mathematical principles. The process of struggling through a derivation on your own is invaluable, as it forces you to connect different pieces of knowledge logically rather than just memorizing results.
Step 3: Comparison — Evaluating and Refining Methods
After completing your derivations, open your textbook and class notes to compare your approach with those presented in the materials or by the teacher. This comparison often leads to valuable insights: perhaps your method is more intuitive, or maybe the textbook’s approach is more elegant and universally applicable. By analyzing the strengths and weaknesses of different methods, you develop a more profound and flexible understanding of mathematical concepts.
Step 4: Generalization — Expanding Mathematical Thinking
True mastery of mathematics extends far beyond simply deriving formulas, proving theorems, or solving problems. It involves questioning assumptions, identifying patterns, and generalizing principles to uncover deeper insights. Consider the Pythagorean Theorem as an example. Memorizing, deriving, proving, and applying the Pythagorean formula for right triangles is just the starting point. To truly grasp its significance, challenge yourself with these thought-provoking questions:
By exploring these deeper questions, you shift from merely using mathematical tools to truly understanding their foundations, limitations, and broader implications. This approach nurtures creativity, critical thinking, innovation, and problem-solving skills — hallmarks of true mathematical mastery.
A Real Example: From Competitive Math to Cutting-Edge Research
One of our students, inspired by this approach, successfully extended the Pythagorean theorem and the Law of Cosines to higher-dimensional spaces and eventually to spherical geometry. Under our guidance, the student refined this work into a rigorous mathematical paper, which we helped recommend for publication in a prestigious journal of the Mathematical Association of America. This outstanding academic achievement became a key stepping stone, ultimately securing the student’s admission to MIT.
Why This Method Works: From Passive Learning to Active Discovery
This structured learning approach — Recall, Derivation, Comparison, and Generalization — transforms passive reception into active engagement. Rather than simply memorizing formulas, you develop a deep contextual understanding and an independent problem-solving mindset. These habits not only enhance academic performance but also cultivate the ability to think critically, explore new ideas, and innovate — skills that extend far beyond the classroom.
Mathematics is not just about solving problems — it’s about discovering patterns, questioning assumptions, and pushing the boundaries of what you know. By following this learning strategy, you will not only excel in math but also develop a lifelong ability to think deeply and creatively.

Learning effectively requires a structured approach. A good study habit includes three essential steps: previewing before class, taking notes during class, and reviewing after class. These are three interconnected and essential steps in the learning process, forming a complete learning cycle. When executed effectively, can significantly enhance your understanding and retention of knowledge.
Previewing Before Class
Before attending a class, students should take time to go through the relevant materials. Previewing helps them get a basic understanding of the topic, identify key points, and formulate any questions they may have.. This preparation not only makes it easier to follow the teacher’s explanations but also enables students to engage more actively in class discussions and absorb new knowledge more effectively.
Taking Notes During Class
During the lesson, taking clear and organized notes is essential. This skill helps students stay focused and systematically organize information. Well-taken notes capture key concepts, important formulas, and explanations that may not be found in textbooks. Writing information in one’s own words enhances understanding and retention, making it easier to review later. Additionally, structured notes serve as a valuable resource for reinforcing learning and preparing for exams.
Reviewing After Class
After class, reviewing the material is crucial for reinforcing what has been learned. Students should go through their notes, clarify any unclear points, and consolidate their knowledge by recalling key concepts and main ideas without referring to their materials. Regular review helps prevent forgetting and promotes a deeper understanding of the subject. Additionally, completing homework assignments and engaging in discussions with classmates can further strengthen their grasp of the material.
Conclusion
These three steps are interconnected and essential for effective learning. Previewing lays the groundwork for understanding new material, note-taking captures key points during the lesson, and reviewing reinforces and solidifies knowledge. By consistently following this cycle, students can enhance their comprehension, retain information more effectively, and improve their academic performance.
Developing this habit not only leads to greater academic success but also cultivates a lifelong ability to learn efficiently. Remember, learning is a continuous journey, not just a destination. By embracing this structured approach and integrating it into your study routine, you can unlock your full potential and achieve your academic goals.
